Description Of The Tree
Botanical Description
The trees are reported to reach heights of 18 to 30 m, with trunk diameters ranging from 90 to 180 cm.
Natural Distribution
This species is reported from Mexico, southward through Central America to Trinidad, Venezuela, Guyana, and Brazil.
Plantations Available?
Enterolobium trees are reported to be often cultivated as ornamentals.
Non Timber Uses
The sawdust from machining is pungent and may cause mucous irritation and allergies.
Wood Identification
Anatomic Description Of Wood
Vessels per mm2 less than 6 (rare). Occasionally vessels with colored deposits. Tangential diameter of vessel lumina 200 micras or more (large). Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma lozenge-aliform. Occasionally septate fibers present.

Workability
Sawing
Sawing of this species is reported to be rather easy, but tension wood may affect this process.
Rotary Veneer Cutting
This species can be peeled and sliced.
Sliced Veneer
This species can be peeled and sliced.
Blunting Effect
The wood exerts slight to moderate blunting effect on cutting tools.
Machining
Guanacaste is reported to be respond well to most machining tools to yield smooth surfaces in most woodworking operations, but surfaces may be woolly because of tension wood.
Planing
Planing is reported to be generally easy, but fluffy wood is common because of tension.
Nailing
The material is reported to nail easily, with good nail holding characteristics.
Polishing
Polishing characteristics are reported to be generally good.
